Wireless Base Station Relay for CoMP Information Sharing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current CoMP transmission/reception systems face delays in sharing base station information due to reliance on wired networks, which also creates a trade-off between communication speed and quality, making it difficult to determine optimal data formats for different modes.
Innovation Solution
A wireless communication system where communication devices acquire uplink and feedback information to determine the necessity of CoMP processing, requesting it from a host-side device and establishing wireless lines with other devices for coordinated multipoint transmission/reception, allowing them to function as relay devices, thereby reducing information sharing time and improving the trade-off between speed and quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If base stations share information through wired network via host device, then communication quality can be maintained, but information sharing time increases causing delay
Solution Approach 1:
The patent replaces the wired network mechanical system with a wireless direct communication system. Base stations directly exchange information wirelessly without routing through the host device via wired connections, thereby reducing information sharing time while maintaining communication quality through direct peer-to-peer communication.
Solution Approach 2:
The patent eliminates the host device as an intermediary in the information sharing process. Instead of base stations communicating through the host device via wired network, they directly communicate wirelessly, removing the intermediary that caused delays in information sharing.
2Speed
If rapidity is required for information sharing, then overhead amount must be suppressed, but communication quality enhancement requires increased overhead
Solution Approach 1:
The patent changes the communication parameters by using wireless direct communication instead of wired network communication. This parameter change allows for optimized data formats that balance overhead reduction with communication quality maintenance, as the wireless direct system can efficiently handle both rapidity and quality requirements without the constraints of traditional wired infrastructure.
3Adaptability or versatility
If multiple CoMP transmission modes are implemented, then communication versatility improves, but difficulty in determining optimal data format increases
Solution Approach 1:
The patent implements a universal wireless communication interface that can handle multiple CoMP transmission modes through a single system framework. This multi-functional approach allows the system to adapt to different transmission modes (joint processing, joint transmission, etc.) without requiring separate data format determination for each mode, thereby reducing complexity while maintaining versatility.

AI summary
The present invention relates to a wireless communication system and a communication control method. The wireless communication system includes: a wireless terminal; a plurality of base stations; and a host-side base station, wherein, in a case where CoMP transmission/reception is requested, the host-side base station decides base stations cooperating therewith for the CoMP transmission/reception, opens wireless lines for base stations under connection to the wireless terminal, and sends a same signal thereto, thereby performs the CoMP transmission/reception, and each of a plurality of the base stations functions as a relay device in a case of transferring the signal with the host-side base station through the wireless line.
